How to suppress the "enumeral and non-enumeral type in conditional expression" warning in GCC

Question

I keep getting this warning from a third-party library (which I don't want to debug), so I'd really appreciate a way to suppress this specific warning. Google failed me, so here I am.

Answer 2

Well, since I couldn't find a way to disable this specific warning, I resorted to using gcc's #pragma system_header. Basically, I wrapped the problematic header like this:

#if defined __GNUC__
#pragma GCC system_header
#elif defined __SUNPRO_CC
#pragma disable_warn
#elif defined _MSC_VER
#pragma warning(push, 1)
#endif

#include "foo.h"

#if defined __SUNPRO_CC
#pragma enable_warn
#elif defined _MSC_VER
#pragma warning(pop)
#endif

where foo.h was the problematic header. Now I just include this fooWrapper.h and the problem goes away. Note that this should work for some other compilers too (MSC and SUNPRO), but I didn't test it.
